What a ridiculous thread. Almost every pop star cares about charts. Yes, even your fave, Taylor Swift, cares about charts. Smash hits equal $$$ for the artist, ofcourse Katy's going to be disappointed when a song she's pushing isn't doing as well as expected.
To answer your question, no. The song was a jingle ad for H&M from start to end. It was never confirmed as a single release so whatever point you're ~trying~ to make, it's null and void.
